The vacuum suction tool is a common mechanical device for conveying workpieces and articles, and has a wide application range. Among the prior art, when adopting the vacuum smoking utensil to adsorb the smoke box and snatch, because the smoke box exists the difference of size and material, including the very heavy scheduling factor of smoke box self, can not avoid taking place the phenomenon that the smoke box dropped in actual smoke box transportation. Because the vacuum suction channel of the existing sucker forms a one-way valve structure by arranging the ball body, when the set vacuum degree is reached, the ball body seals the suction channel so as to reduce the load of a vacuum system. And whole smoke box transport district belongs to the automation mechanized operation, and when absorbing smoke box deformation or smoke box and dropping in the transportation like this, because the effect of check valve, there is the hysteresis in the reduction of the vacuum of system, leads to the monitoring personnel not in time to discover, therefore can't make as early as possible and handle, finally leads to more economic losses.

Disclosure of Invention

The utility model discloses it is exactly to having the vacuum to inhale the problem that whether has the smoke box to detect in the transportation to the utensil is inhaled in current vacuum, and provides a vacuum inhale the utensil for falling a detection.

In order to achieve the above purpose, the technical scheme of the utility model is as follows: a vacuum suction tool for falling piece detection comprises an external air extraction interface, a vacuum rack and a sponge sucker which are sequentially installed from top to bottom, wherein a plurality of first channels and at least one second channel for vacuum adsorption are formed on the vacuum rack and the sponge sucker together; the first channel is of a multi-section structure with two small ends and a large middle part, and a ball body for forming a one-way valve is arranged in the first channel; the second channel is of an unblocked structure and is used for forming a leakage detection channel.

The utility model provides a vacuum suction tool for falling a detection is provided with the spheroid that is used for constituting the check valve in first passageway, and the second passageway is unblocked structure for constitute the leak testing passageway. When the sponge sucker is attached to the top of the smoke box, the smoke box and the sponge sucker are sucked together by negative pressure by using a vacuum pump to pump vacuum outwards, and the leakage detection channel is also sealed by the surface of the smoke box; the vacuum degree is kept within a set range, and the tobacco box transfer is completed. After the vacuum degree reaches a set value, the ball body overcomes the gravity to rise and is blocked at the small hole at the upper end of the first channel under the action of vacuum adsorption force. When the smoke box along with vacuum chuck transportation in-process, box top surface deformation appears because of box self quality problems or the action of gravity that receives the incasement cigarette, or when the unexpected collision piece condition, sponge sucking disc and smoke box surface appear the gap, then leak detection passageway and external atmospheric environment intercommunication, make the vacuum of vacuum frame reduce rapidly, the hysteretic hidden danger of vacuum reduction has been eliminated, thereby the accessible detects the vacuum size and reduces to the vacuum and warns, if carry out sound, light, electric alarm etc. so that in time handle, eliminate the hidden danger, avoid causing bigger economic loss.

Further, the leakage detection channels are two arranged in the middle. Therefore, the leakage detection channels are arranged in the middle and are two, and the smoke box can be timely and accurately judged whether to fall off or not under the condition that normal adsorption is not influenced; if the adsorption is unstable or the piece falls, the vacuum degree can be rapidly reduced by 30 percent through verification, so that an alarm is triggered to find out in time and take countermeasures.

Further, the middle section is arranged on the vacuum rack. The vacuum frame is made of light materials, but the strength of the vacuum frame is obviously higher than that of a sponge sucker. Therefore, the middle section for mounting the ball body is arranged on the vacuum frame, so that the service life can be effectively prolonged.

Further, the second channel is identical in structure to the first channel. The first channel and the second channel can be formed by adopting the moulds with the same structure, so that the manufacturing difficulty and the manufacturing cost are reduced.

Has the advantages that:

the utility model provides a vacuum suction tool for falling a detection is provided with the spheroid that is used for constituting the check valve in first passageway, and the second passageway is unblocked structure for constitute the leak detection passageway, thereby the accessible detects the vacuum size and reduces to vacuum anomaly and warns, if carry out sound, light, electric alarm etc. so that in time handle, eliminate the hidden danger, avoid causing bigger economic loss.
